Next time you're in central London, PM me and bring it with you. I'll measure the output for you with my newly calibrated laserbee.

This is only a rough measurement.... 2.0505220604755174 mRad

5mm @ aperture, 25mm @ 32 feet

This is a good example of "calculations carried out to greater accuracy than that of the original data, or measurements reported to a greater precision than the equipment supports" :thinking::p

Significant figures
